I disagree with the people who complain about the calculator taking too much time. It's good to see how the calculations are done as it helps with the understanding of it .It also gives you a chance of thinking about what was said and making sense of it in your head.
I'm just now beginning to learn mass defect, I have been studying General Chemistry ⚗️🧪 which includes a little Physics and I must say once 🔂 you learn it this type of science 🔭 is a piece of cake 🍰 my friends 🎈
As many of them are confused regarding electron mass exclusion, the species that is shown up here is a Helium nucleus which was obtained from alpha decay. Hence, it has no electrons in it. Watching the video on types of decay can provide more clarity.
Thank you for the explanation, I can now say that calculating the mass defect is more intuitive. There is one question I'd like to ask, if you don't mind. Should the energy which has been released have a "-" sign in front of it? Some textbooks I've read have instructed the reader to do so, while others don't seem to really care.
***** I too thought it was a little weird that a negative sign should denote a release of energy. I guess I'll just have to learn to be adaptable with any school that I attend like you mentioned. Thanks for the reply
Learnt a lot from this video, but I have a quick question: Why is it that the neutrons and protons must lose mass and convert it into energy in order to become a nucleus? Sorry, I'm just starting to dive into all this ^ ^;
The answer lies in what does it form after the energy is released. The " binding energy has its existence on the mass defect ( mass converting into energy) so just imagine now for a second where you have no binding energy and are able to remove any number of protons or neutrons from the nucleus. This will create a havoc in the Physical world !!
In Nuclear fission When the neutron hits the nucleus of u-235 some particle's(either one of proton's or neutron's mass in u-235 nucleus is bieng converted to energy right??)But the question is is it one of proton in u-235 nucleus or one of neutron in u-235 nucleus???
This proved that nuclear fusion can create energy in return for a loss of mass from the quarks. I fail to understand (considering nuclear binding energy) why does nuclear fission also create energy? A simple assumption would be that fission would eat up the binding energy, and give none in return.
energy of repulsion between protons and neutrons is greater thus overcoming binding energy and the extra energy is released along with the product of the splitting of the heavy nucleus
sometimes they'll provide atomic mass (neutrons, protons, and electrons). in this case subtract mass of electrons from atomic mass. mass one electron ~ 5.486042 x 10^-4 amu
Christopher Kenshin Manong Yeah but it would take 1837 electrons to make up the mass of 1 proton...this means that the atomic number of the atom would be 1837( an atom is electrically neutral) .However such an atom does not exist
It would be better if you just summarize all your work with a formula at the end because no body can memorize those strings of numbers you presented. Also, it is kind of senselessly to include so many significant figures in your calculation. Seeing that many numbers on the screen can only give people headache, and I guarantee nobody would actually read it number by number. You are only demonstrating how to calculate binding energy, it is the method that counts.
Sal! a quick question..What is the source of energy aka mass defect.I mean from where does this energy comes.Does it comes from bond energetics - via YTPak(.com)
They had to consider all learners not just the fast ones. It's boring for us who go faster, but it would be very hard for those who go slow if the explanations were super fast.

4:29 mass defect
5:51 conversion
10:43 nuclear binding ey
Thank you, I been looking for a video like this for probably about an hour now and this finally cleared my confusion
loving the video, buh the calculator takes tym, it b better if there were Done b4

I love you yar. You really saved my life. It helps me very much in my exams practice. Thank you so much
This is sooo helpful!
Thanks a lot :)
Thank you so much for the great explanation! :)

This video really helped me thanks 😊
I love this, I understand it now
You are rascal
Great video

Wow..Thats awesome and easy...
What is the difference between mass defect and mass difference
It's the same thing.
Thank you so much Sir
This is helpful
Great job! :)
Great explanation.
Is it correct for mass defect to be negative?
How would you know the number of protons and neutrons if the only available data is the amu of the element?
Shouldn't we also need to include electron mass in the predicted?
Since when are there any electrons in a nucleus?
No its small enough to not hold a significant effect on results

next video of calculating mass of an object plz
How do I find the actual mass for a nucleus? Is it given?
Jojo 317 usually it is yes
sometimes they'll provide atomic mass (neutrons, protons, and electrons). in this case subtract mass of electrons from atomic mass. mass one electron ~ 5.486042 x 10^-4 amu
do you not have to worry about electrons??
Ethan electrons have negligible mass, so we don’t care about electrons ( electron mass=1/1837 amu)
@@meltdown6856 but electrons can still affect the predicted mass especially those who have higher electron count
Christopher Kenshin Manong Yeah but it would take 1837 electrons to make up the mass of 1 proton...this means that the atomic number of the atom would be 1837( an atom is electrically neutral) .However such an atom does not exist
He did! Electrons are accounted for in amu calculations (:
for the mass defect calculation, dont u add the amu of electrons while predicting and then subtract that from the actual?
mass defect is related only with nucleus of the atom so it will consists of the masses of just nucleons ( proton and neutrons ) and not electrons.
@@fancymonkey3195 my book also states to add the electrons into mass defect... I am confused
Great
What's the mass of an electron in atomic mass unit ?
0.00054858 a.m.u
Why do you not take into account the mass of the electrons?
electrons are incredibly light and hence negligible
this was mass defect with a helium nucleus ie protons and neutrons, no electrons
The mass of Electrons is never added when it comes to Nuclear chemistry because it's so light
He did! Electrons are accounted for in amu calculations (:
How can we get the actual mass?
Thanks alot
nice!
how did you get the actual mass? im confused
Can you still find the energy even when using the atomic mass unit?
E = (mass defect in amu) * c^2
then the energy u found wouldn't be in Joules
Prashanth Prashobh What would it be in then? Electron Volts I'm guessing?
Yeah, eV
Prashanth Prashobh What's the equation?
The one I just posted or something else?
it's the exact same, but as said it would be (1amu)(1m\s) which, as you've noted, results in 1eV instead of 1 J.
how did we get the actual?
it's should be given in the question
How do u write actual mass
To convert energy from J to MeV would I multiply by 6.242×10^12?
Cameron Leonard 1 Mev= 1.6×10^-13 J
Why did u do only neutron and proton and not electron
Can't you leave the mass in amu's and put the speed of light at just C^2. You will get the energy in the form of eV.
No, for eV you need to multiply amu by 931
Cool!!!
Mass of proton is incorrect .. i think
Where are the 2 electrons?
They are only talking about the nucleus not the whole atom. There are no electrons in the nucleus
he has to say every number
why did he use light?
as a representation of anything?
Since AAMC does not allow use of calculator in MCAT, why cant you teach WITHOUT the tool? Does MCAT provide the long conversion factors?
How does mass convert into energy?

Mohammad Bilal strong nuclear I think
how did you get those 1.007 blah blah. is it constant?
+Edgar Maraon yep
+Edgar Maraon yes they are.
it's quite slow. can't u speed up explanations
tip for free, just use the speed up mechanic on the video (like i do on most slow videos) change it to 1.25 or 1.5

so tedious >.
11 mins of the guy just rambling. Man..
This isnt kitty 0706
Mass can't be converted to energy ...no this ain't alchemy .....mass is energy ......or mass is a property that all energy exhibits.
So wrong lmao
u guys waste so much time while doing calculations
The calculations are important in chemistry of any form, so they have to do them. They also explain them for those who have trouble with the calculations.
Explaining everything for those who are learning. SMH
they want that 10 minute mark, more ad revenue
Michael Gemmill there are no ads on the vids tho...
Bruh why did you take so much time to calculate?? Immediate dislike
so tedious>.
